CAP SPINNING AND TWISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 335,385, dated February2,1886.

Serial No. 178,703. (No model.)

To all whom it may concern:

Be it known that I, WALKER RILEY, a citizen of the United States,residing at Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a certain new and useful Improvement in CapSpinning and Twisting Machines, of which the following is aspecification.

My invention rela-tes to cap spinning and twisting` machines; and itconsists in the improved means, hereinafter described, of driving thewhirls and bobbins or spools of the same.

In the accompanying drawings, Figure 1 is an end elevation of as much ofa cap-spinning machine provided with my improvement as is necessary forunderstanding said improvement, the upper part of the frame being brokenaway, and the corner parts of the frame being broken away to show thelifting mechanism, the spindles, spools, whirls, and caps; Fig. 2, aside elevation of a part of the frame and the driving and liftingmechanism, with spindles, whirls, spools, and caps; Fig. 8, a sideelevation of a part of the bandpulleys and their shafts.

A is the frame of the machine. B B are vertical stationary or deadspindles; C C, stationary caps or tubes having closed upper ends andresting upon the tops of the spindles, the caps usually having conicalholes in their upper ends, which receive the tapering upper ends of thespindles; D D,whirls,which support the bobbins or spools E E(warp-spools are represented in the drawings) and rotate the same; FF,cops on said spools; GG,wash ers surrounding the spindles loosely andsupporting the whirls; H H, horizontal lifterplates, one on each side ofthe machine, on which the washers G G rest, and which being raised orlowered raise or lower said washers, whirls, spools, and cops, whenraised carrying vthe spools and cops up into the caps, the friction ordrag of the yarn on the caps causing twisting of the yarn, the lower endor edge of the caps guiding the yarn onto the spool, and causing it tobe wound evenly between the heads of the same; I I, vertical-lifterrods, (of which there are several on each side of the machine) the upperends of which are secured to the lifter-plates H H, and the lower endsof which are provided with horizontal arms 'i i, to each of which isattached one end of a lifter-chain, J, (there being as many chains J asrods I, one being shown in Fig. 2,) which chain J, being carried overpulleys j j, is attached at the other end to a horizontally-sliding rod,K, (there being one such rod at each side of the machine,) thelifter-lever L having a fulcrum, Z, at its lower end, and at its upperend connected to said rod K and provided with a projection, Z', againstwhich another lever, M, (pivoted at its upper end,)is pushed by therevolution of the heart N, to slide the rod K and lift the whirls andspools. The heart or cam N, secured on the same shaft n with theworm-gear O, and caused to rotate by the worm O, are all of the usualconstruction and operation, except as hereinafter stated.

The spindles, bobbins, whirls, and caps are commonly arranged in tworows, as shownone row at each side of the machine-and the whirls andbobbins are caused to rotate by bands (a separate band for each whirl)connecting said whirls and a band-cylinder which runs from end to end ofthe machine, near the middle thereof, and serves to drive all of saidwhirls and spools. As the band-cylinder rotates around a stationaryhorizontal axis, the rising and falling of the whirls stretches thedriving-bands, the tension of these bands being least at the middle ofthe traverse. \Vhen the whirl is at the top of its traverse, the tensionof the driving-band is so great as to bend the dead-spindles with theircaps toward the band-cylinder. It will be seen that the commonconstruction of the whirl-driving mechanism causes the spools and whirlsto traverse in an arc instead of in a straight line, requiring morepower to drive the whirls and spools, and greatly limiting the length ofthe traverse; in other words, limiting the length of the spool, andtherefore limiting the capacity of such spool for holding yarn, thelength of the traverse being the distance between the heads of a spool.Itis desirable that the spindles should stand vertically, in order thatthe friction of the yarn on the cap may be the same on every side of thecap during the entire traverse. The defects complained of might beremedied by making the spinning-frame IOC wider, and so making thedistance between the spindles and the band-cylinder` greater 5 but thiswould make the machine more bulky and cause it to occupy morefloor-space. I attain the same or a better result by dispensing entirelywith the band-cylinder, and using instead thereof two series of groovedband-driving pulleys, P, having about the same diameter as the ordinaryband-cylinder. The grooved pulleys P are secured on two shafts, Q,placed as near as conveniently may be to the rows of spindles, and thewhirls of each row are revolved by bands R, which pass around them andaround the grooved pulleys P farthest from them, above and below theshaft of the other series of grooved pulleys and in the intervalsbetween said last-named pulleys. The greater the distance between thewhirls and the band-pulley the more nearly uniform will be the strain ofthe driving-band throughout the entire traverse, because the arcdescribed by the whirl, connected by a driving-band to the band-pulley,and perfectly free to move in an arc about the axis of said pulley,would be more nearly straight for a given length of traverse the greaterthe distance between said whirl and aXis. The distance, however, towhich one series of bandpulleys may be set from the whirls driven bythem is limited by the fact that the drivingbands of the oth er seriesof whirls must be free to rise and fall without striking the shaft ofthe' With the above-described arrangement and construction bobbinsandspools may be made twice as large, or, in other words, the traversemay be twice as long, with less wear and tear of the bands. rPhe effectof using twice as large spools or bobbins is, that less piecing of theyarn is required, and there will be fewer knots in theyarn, the clothmade from the yarn will be more free from broken picks, thespinningmachine will need to be stopped less frequently for do'fng, theloom will require to be stopped less frequently on account of bad work,and the production of the mill will consequently be greatly increased.

The improvement above described causes less wear of the bands of thefianges of the whirls, and the increased length of the bands gives themgreater elasticity and makes them less liable to draw the spindles andcaps out of position.

' The invention above described is equally useful for drivingfilling-bobbins.

I claim as my invention- A spinning-machine having two parallel rows ofdead-spindles on opposite sides thereof', whirls free to turn on saidspindles and to rise and fall thereon, and to engage with and to rotatespools or bobbins surrounding said spindles, two series of band-pulleys,two.

parallel shafts arranged between said rows of spindles7 to each of whichshafts is secured one of said series of pulleys and two series ofdriving-bands, each series of such bands passing around the whirls ofone row and around the band-pulleys of the series farthest from suchwhirl, and above and below the shaft of the series of band-pulleysnearest such whirl, and between the pulleys of said last-named series,as and for the purpose specified.
